Vect * -1 will give you a vector that points in the opposite direction of the original vector. -- Jeffrey "botman" Broome ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
Re: [hlcoders] Inverse Vector
From what I gather by reading a rather outdated version of vector.h,
you can call Negate() to invert an existing vector; or, if you don't
#define VECTOR_NO_SLOW_OPERATIONS, you can create a new negated vector
by calling {v2 = -v1;} (the canonical negation operator.)
To be sure, just check public/vector.h.

Umm... that should be correct; that'll give you the vector of the same magnitude (length) going in the opposite direction. (That *is* what you're looking for, yes? If not, you'll have to describe it, since I think you're using the wrong term.) -- Andrew Timson == "Niceness is the greatest human flaw, except for all the others." --Brendan Moody ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
